Carbon Offset Providers

offer Verified Carbon Offsets, aka Verified Emissions Reductions (VERs), which are claimed reductions in carbon emissions (balanced against carbon emissions) that are audited by an independent third party and satisfy a particular criteria established for regulatory purposes or by a voluntary offset certifier.
A Verified Emission Reduction (VER) is a reduction of one ton of greenhouse gas carbon equivalent.

CCAR California Climate Action Registry
Climate Action Reserve is a program of the California Registry, a private non-profit, which tracks and registers voluntary projects that reduce emissions of GHGs. Has developed credible, accurate, and consistent GHG reporting standards and tools for organizations to measure, monitor, third-party verify and reduce their GHG emissions consistently across industry sectors and geographical borders.
CCBS Climate, Community & Biodiversity Standards
Climate, Community and Biodiversity Alliance has developed voluntary standards to help design and identify land management projects that simultaneously minimize climate change, support sustainable development and conserve biodiversity.
CCX Chicago Climate Exchange ent.jsf?id=23
Chicago Climate Exchange is currently North America’s largest voluntary “cap-and-trade” program. See CCX Rulebook.
CDM CDM (CERs) Developing countries
United Nations Framework Convention on Climate Change
Predominantly large scale projects that are UN backed. Projects undergo rigorous bureaucratic board procedures.
CER Certified Emission Reductions The Clean Development Mechanism (CDM) market, a trading scheme set up during the Kyoto Protocol, allows companies from rich nations to invest in clean energy projects in developing countries and in exchange they receive Certified Emission Reductions (CERs), which they have the option of using toward their emissions targets or selling for a profit.
CR Climate Registry
The Climate Registry is a nonprofit North American partnership developing an accurate, complete, consistent and transparent greenhouse gas emissions measurement protocol that is capable of supporting voluntary and mandatory greenhouse gas emission reporting policies for its Members and Reporters. It will provide a verified set of greenhouse gas emissions data from its Reporters supported by a robust accounting and verification infrastructure."
CRS Center for Resource Solutions
CRS, a nonprofit,  designs policies, identifies best practices and creates implementation tools that promote renewable energy generation and ensures validity.
DOE US Dept of Energy. HGregistry/generalguidelines.html Voluntary Reporting of Greenhouse Gases Program, U.S. Department of Energy, Office of Policy and International Affairs.  General Guidelines for the Voluntary Reporting of Greenhouse Gases (1605(b)) Program first published in the Federal Register April 2006, corrected Jan 2007.
EPA EPA's Climate Leaders program
Climate Leaders is an EPA industry-government partnership that works with companies to develop comprehensive climate change strategies.
ERT Environmental Resources Trust
ERT built the world's first private non-profit emissions registry in 1997. Rigorous but streamlined process to enable cost-effective registration of high quality GHG inventories and Verified Emission Reductions.''
GeE Green-e Energy
Green-e Renewable Energy Certification Program administered by the Center for Resource Solutions, a nonprofit,  is a voluntary certification program that sets consumer-protection and environmental-integrity standards for greenhouse gas(GHG) emission reductions sold in the voluntary market. Green-e Energy is the nation's leading independent certification and verification program for renewable energy.
GS Gold Standard***
Used for both UN backed programs and voluntary credits
The Gold Standard is a non-profit foundation initiated by WWF, SSN and Helio International, launched in 2003. Gold Standard offers a quality label (higher sustainable development credentials than required by the CDM rules) to CDM/JI and voluntary offset projects and is supported by a group of 51 NGOs/charitable organizations. Hosted by a UNEP Collaborating Centre.
Gold Standard Clean Development Mechanism (CDM)
Kyoto-UN Backed.  Backed by 50+ NGOs/charities. Predominantly large scale projects like CDM but with strong focus on GHG at its source, sustainable development and community projects in developing countries.
GS VERs Gold Standard Voluntary
Countries without a Kyoto target
Backed by 50+ NGOs/charities. Rigorous high quality standards for the voluntary market. Based on CDM but without needing board authority. Marketplace for GS Offset Providers.
VERs Verified Emission Reductions
Also referred to as Voluntary Emission Reductions.
A unit of emission reductions that has been verified by an independent auditor to a recognised standard. A one unit reduction is equivalent to one ton of CO2 greenhouse gas.
VCS Voluntary Carbon Standard
Voluntary Carbon Standard was initiated by The Climate Group, the International Emissions Trading Association and the World Economic Forum in late 2005. Rigorous but appropriate voluntary market standard.
means that a project would 'not' have gone ahead without carbon credit funding. If a project is financially viable without carbon financing, it is not considered additional.

Pew Center. "Ensuring Offset Quality, Integrating High Quality Green House Gas Offsets into North American Cap and Trade Policy" Offset Quality Initiative offers policymakers practical recommendations for the integration of greenhouse gas offsets into emerging regulatory systems at the state, regional and federal levels. (July 2008)  This report discusses the advantages and disadvantages of voluntary carbon offsets as a mechanism for reducing GHG emissions. It defines offsets and explains what makes a ‘quality offset’. It describes the various standards for offsets, explains how the market operates, and lists the main providers and purchasers. ng-Offset-Quality-white-paper.pdf Pew Center.  "Ensuring Offset Quality, Integrating High Quality Green House Gas Offsets into North American Cap and Trade Policy" Offset Quality Initiative offers policymakers practical recommendations for the integration of greenhouse gas offsets into emerging regulatory systems at the state, regional and federal levels.
